Hydroseeding is an alternative to the traditional process of broadcasting or sowing dry seed. A study conducted along the lower Colorado River in Arizona reported that hydroseeding could be used to restore riparian vegetation in cleared land. [2] The slurry often has other ingredients including fertilizer, tackifying agents, fiber mulch, and ...
Conversion and its related terms yield and selectivity are important terms in chemical reaction engineering.They are described as ratios of how much of a reactant has reacted (X — conversion, normally between zero and one), how much of a desired product was formed (Y — yield, normally also between zero and one) and how much desired product was formed in ratio to the undesired product(s) (S ...
In chemistry and physics, the dimensionless mixing ratio is the abundance of one component of a mixture relative to that of all other components. The term can refer either to mole ratio (see concentration ) or mass ratio (see stoichiometry ).
Slurry transport uses several methods: hydraulic conveying; conventional lean slurry conveying; and high concentration slurry disposal (HCSD). The latter, HCSD, is a relatively modern approach, which is used to transfer high throughputs of fine fly ash over long distances (>10 km or 6.2 mi) using high pressure diaphragm pumps with velocities of around 2 m/s.
Mixing of liquids occurs frequently in process engineering. The nature of liquids to blend determines the equipment used. Single-phase blending tends to involve low-shear, high-flow mixers to cause liquid engulfment, while multi-phase mixing generally requires the use of high-shear, low-flow mixers to create droplets of one liquid in laminar, turbulent or transitional flow regimes, depending ...
Hydrosprigging, similar to hydroseeding, is the use of sprigs or cut stolons and rhizomes in a slurry of fertilizer, mulch, and binding agent, sprayed with a hose over a target area. [1] This can be effective in areas sensitive to soil surface disturbance, such as eroding shorelines, hillsides or other slopes of varying steepness, or in ...
The density of the slurry mix must be carefully monitored and adjusted to produce the correct outward pressure to prevent the trench walls from collapsing. Slurry walls are typically constructed by starting with a set of concrete guide walls, typically 1 metre (3 ft 3 in) deep and 0.5 metres (1 ft 8 in) thick.
The PFR model works well for many fluids: liquids, gases, and slurries. Although turbulent flow and axial diffusion cause a degree of mixing in the axial direction in real reactors, the PFR model is appropriate when these effects are sufficiently small that they can be ignored.
